Browser Use Cloud Reference

SkillWeb & browsing

Documentation reference for using Browser Use Cloud — the hosted API and SDK for browser automation. Use this skill whenever the user needs help with the Cloud REST API (v2, v3, or v4), browser-use-sdk (Python or TypeScript), X-Browser-Use-API-Key authentication, cloud sessions, browser profiles, profile sync, CDP WebSocket connections, stealth browsers, residential proxies, CAPTCHA handling, webhooks, workspaces, skills marketplace, liveUrl streaming, pricing, or integration patterns (chat UI, subagent, adding browser tools to existing agents). Also trigger for questions about n8n/Make/Zapier integration, Playwright/ Puppeteer/Selenium on cloud infrastructure, or 1Password vault integration. Do NOT use this for the open-source Python library (Agent, Browser, Tools config) — use the open-source skill instead.

What this skill tells your AI

The instructions your AI receives, as published by browser-use/browser-use in skills/cloud/SKILL.md and read by ahel’s review.

Reference docs for the Cloud REST API, SDKs, and integration patterns. Read the relevant file based on what the user needs.

Choose a starter

  • Hosted task in, result out: use the V4 SDK runs resource in references/api-v4.md.
  • Your existing agent needs a browser: use the V4 SDK browsers resource or REST/CDP, then explicitly stop the browser.
  • Local framework development: use the open-source browser-use skill, not Cloud SDK calls.

Eligible new Google, GitHub or Microsoft signups get a one-time $15 Cloud credit. No card required; email/password signups do not qualify. Pricing and eligibility. Use gpt-5.6-luna for the free starter; paid-only models need a top-up.

Reuse BROWSER_USE_API_KEY, or guide the user through Cloud signup and key creation. Keep keys server-side, never in prompts or client bundles.

Critical Notes

  • Use v4 for new hosted-agent integrations. Keep v2 or v3 only when maintaining an existing integration or using a resource not yet wrapped by the v4 SDK.
  • Cloud API base URL: https://api.browser-use.com/api/v2/ (v2), https://api.browser-use.com/api/v3 (v3), or https://api.browser-use.com/api/v4 (v4)
  • Auth header: X-Browser-Use-API-Key: <key>
  • Get API key: https://cloud.browser-use.com/new-api-key
  • Set env var: BROWSER_USE_API_KEY=<key>
  • Cloud SDK: uv pip install browser-use-sdk (Python) or npm install browser-use-sdk (TypeScript)
  • Python v2: from browser_use_sdk import AsyncBrowserUse
  • Python v3: from browser_use_sdk.v3 import AsyncBrowserUse
  • Python v4: from browser_use_sdk.v4 import BrowserUse or AsyncBrowserUse
  • TypeScript v2: import { BrowserUse } from "browser-use-sdk"
  • TypeScript v3: import { BrowserUse } from "browser-use-sdk/v3"
  • TypeScript v4: import { BrowserUse } from "browser-use-sdk/v4"
  • SDK 3.11.3 or newer exposes browsers.create and browsers.stop in the v4 namespace, alongside the v4 REST /browsers resource. Always stop a browser explicitly; closing CDP does not stop billing.
  • CDP WebSocket: wss://connect.browser-use.com?apiKey=KEY&proxyCountryCode=us
